Bow of Argas

The Bow of Argas appears to be a 5' long staff.
When held by the mid point it turns into a glowing stringless composite long bow.
On command of the wielder a string and arrow appear.
The arrow is effectively +4 to hit & damage.
The bow tunes itself to the users strength each day by 1 strength catagory per arrow fired starting at 9 strength.
The bows fire rate is 5/2.
Long range is extended by 10 foot/yards per tuned strength catagory above 9.
The bows strength bonus resets itself at midnight.
The bow cannot be used with normal arrows.
Once the bows tuning reaches the point where the user gets strength bonuses it cannot be used by characters that have a lower strength that day.
